IMPROVEMENT IN HOOP-FAST'ENERS.

Specification forming part of Letters Patent No. 210,482, dated December3, 1878; application filed April 15, 187s.

To all whom t 'may concern:

Be it known that l, ALBAN ANDRN, of Beverly, in the county of Essex andState of Massachusetts, have invented certain new and usefulImprovements in Ho op-Fastenings; and I do hereby declare th at thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters -of reference marked thereon, which forma part of thisspecification.

My invention relates to improvements iu hoop-fastenin gs forbarrel-hoops of that kind in which one end of the hoop is laid outsideof the other end and united by means of nails or rivets; and this myinvention consists in a hoop-fastening composed of a staple having anelongated central clinch-nail, the prongs or arms and loops of thestaple being for the purpose of embracing the top end of the hoop, andthe elongated central nail adapted to be driven through both ends andclinched upon Y of a clinch-nail and a washer, outside of which has beendriven an ordinary staple, embracing the outer piece of the hoop andentering the inner one, so as to prevent the end of the hoop fromsplitting, which arrangement necessitates a twofold manipulation by theworkman in driving at one time a clinch-nail and washer, and, secondly,a staple between the extreme end of the outer part of the hoop and theclinch-nail aforesaid; whereas with my improved fastening only onemanipulation is necessary-namely, to drive the center plece -of theT-nail and clinch it on the under side of the inner part of the hoop atthe same time as the side projections are driven, so as to elnbrace theouter hoop part.

I do not confine myself' to any exact proportion of the length of thecenter piece ofthe T- nail as compared with its side pieces, as thelatter may be either of such a length as to enter the under part of thehoop just alittle, or just touch it without entering, or not touch it atall, as may bedesired for various kinds of work or for differentpurposes.

' On the. accompanying drawings, Figure 1 represents a plan view of apart of a hoopjoint provided with my improved fastening. Fig. 2represents a side elevation of the same. Fig. 3 represents across-section of the fastening 011 the line A B, shown in Fig. 1. Fig. 4represents a side view of my improved T nail, and Fig. 5 represents theT-nail as being made of wire bent into shape similar to the solid oneshown in Fig. 4.

Similar letters referl to similar parts wherever they occur on thedifferent parts of the drawings.

c represents the outer part of an ordinary hoop, and b represents theinner or under part of such hoop. c crepresent the nails uniting thehoop parts in the ordinary way. d represents my improvedT-nailfastening, having a center part, d', and side pieces, d d, as and forthe purposes set forth.

In Fig. 3 the center piece, el', is shown as being clinched, and havingthe side pieces, d d", embracing` the outer hoop part, a, and drivenlightly into the upper side of the under hoop-piece, b, as shown; butthe said side pieces, d d", may be m'ade not quite so long in proportionto the center piece, d', in which case they would only embrace the outerhoop part, a, without touching the lower hoop part at all.

These nails may be forged, punched, droppcd, or bent solid, or made ofdoubled-up wires,

Ihat I wish to secure by Letters Patent,`

and claim, is-

The hoop-fastening eonsistingof the staple l Ahaving the short prongs1f/,adapted to emmy own invention I have affixed my signature brace theouter and slightly penetrate the inin presence of two Witnesses.
